Abstract：Objective To explore the relationship between nutritional parameters and the risk of major adverse cardiovascular events(MACE)after PCI in elderly patients with acute myocardial infarction.Method A total of 596 elderly patients with acute myocardial infarction who underwent PCI at the Affiliated Hospital of Southeast University from December 2021 to December 2022 were selected.After 6 months of follow-up,the patients were divided into the MACE group(114 cases)and the NMACE group(482 cases)based on the presence or absence of MACE.Single factor and multivariate logistic regression were used to analyze the factors related to MACE occurrence in patients,and the receiver operating characteristic curve(ROC)was used to evaluate the predictive value of different parameters for MACE occurrence in patients with acute myocardial infarction after PCI.Results The history of diabetes,coronary heart disease,combined heart failure,Killip grade,left main artery disease,EF value,fasting blood glucose,NRS-2002 in the MACE group were higher than those in the NMACE group(P＜0.05),and total cholesterol,albumin,low-density lipoprotein,hemoglobin,lymphocyte ratio,GNRI were lower than those in the NMACE group(P＜0.05).GNRI,total cholesterol,EF value,albumin were protective factors for MACE.NRS-2002,Killip grade Fasting blood glucose is a risk factor for MACE.The ROC curve shows that the AUC of GNRI combined with NRS-2002 and albumin for predicting MACE is 0.872(95％CI:0.845～0.900),sensitivity is 91.0％,and specificity is 81.3％.Conclusion GNRI,NRS-2002,albumin are closely related to the occurrence of MACE after PCI in elderly myocardial infarction patients,and improving nutritional levels may be beneficial for reducing the occurrence of MACE.
